Title:
STEPPING MOTOR
Document Type and Number:
Japanese Patent JP2015046966
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a claw pole stepping motor with a sensor in which the rotation angle of a rotor can be detected by using a part of a rotor magnet without compromising the performance, and high location accuracy can be ensured even when a coil is energized.SOLUTION: A stator unit 6 is constituted of a first stator 31 and a second stator 32 arranged in the axial direction, and a sensor attachment part 33 provided between both stators 31, 32. A first magnetic flux detection sensor 121 and a second magnetic flux detection sensor 122 for detecting the rotation angle of a rotor 7 by detecting the magnetic flux from the rotor 7 are provided in the sensor attachment part 33, and both magnetic flux detection sensors 121, 122 are arranged while being sandwiched between adjacent first stator 31 and second stator 32. Each magnetic flux detection sensor 121, 122 is configured to face the outer peripheral surface of the rotor 7 arranged on the inside of the sensor attachment part 33.
